Abstract

Metal–organic frame materials (MOFs) create ordered spatial structures through organic bridges and metal ion centers. This microstructure can effectively disperse the active centers. In this work, CuCo-MOF was firstly prepared by hydrothermal method and then physically mixed with MoS₂. The prepared materials were applied to study the catalytic performance for oxygen evolution reaction (OER). The results show that the overpotential and Tafel slope of CuCo-MOF/MoS₂ are 336 mV and 75 mV dec⁻¹. The addition of MoS₂ can effectively reduce the stacking of MOFs and increase the effective contact area with the reactants and promote charge/mass transport as well as enhance the catalytic activity. In addition, MoS₂ has strong viscosity, and when it is mixed with MOF, the stability of the composite can be improved. The good OER performance of CuCo-MOF/MoS₂ provides a reference for the exploration of a novel OER catalyst.

CuCo-MOF/MoS2作为析氧反应的高性能电催化剂

金属有机框架材料(MOFs)通过有机桥梁和金属离子中心创造有序的空间结构。这种微观结构能有效分散活性中心。本文首先采用水热法制备CuCo-MOF，然后与MoS2进行物理混合。将所制备的材料应用于析氧反应(OER)的催化性能研究。结果表明:CuCo-MOF/MoS2的过电位和Tafel斜率分别为336 mV和75 mV dec−1;添加MoS2可以有效减少mof的堆积，增加与反应物的有效接触面积，促进电荷/质量输运，提高催化活性。此外，MoS2具有较强的粘度，与MOF混合可提高复合材料的稳定性。CuCo-MOF/MoS2良好的OER性能为开发新型OER催化剂提供了参考。

期刊介绍： Electrocatalysis is cross-disciplinary in nature, and attracts the interest of chemists, physicists, biochemists, surface and materials scientists, and engineers. Electrocatalysis provides the unique international forum solely dedicated to the exchange of novel ideas in electrocatalysis for academic, government, and industrial researchers. Quick publication of new results, concepts, and inventions made involving Electrocatalysis stimulates scientific discoveries and breakthroughs, promotes the scientific and engineering concepts that are critical to the development of novel electrochemical technologies. Electrocatalysis publishes original submissions in the form of letters, research papers, review articles, book reviews, and educational papers. Letters are preliminary reports that communicate new and important findings. Regular research papers are complete reports of new results, and their analysis and discussion. Review articles critically and constructively examine development in areas of electrocatalysis that are of broad interest and importance. Educational papers discuss important concepts whose understanding is vital to advances in theoretical and experimental aspects of electrochemical reactions.
